The diameter of the pores must be sufficient to ensure sufficient air permeability, and the diameter must be optimal for the electrode reaction occurring at the interface between the electrolyte or ion exchange membrane and the electrode. The type of catalyst used, the type of electrolyte or ion exchange membrane used Must be made to the optimum diameter according to In the above description, the fuel cell has been described as an example, but the conductive carbon porous body is not only applied to the electrode of the fuel cell, but also has conductivity,
It is also an important component for other chemical plants that require breathability, chemical resistance and mechanical strength.
